verifica daca egaltatea este adevarata12×[25÷(35+25-7×5)+16÷4-60=0 ex nr2.[(20-1+19-2+18-3+17-4)×10+336]÷976×101

Răspuns :

12*[25/(35+25-35) +4-60 = 0
12*[25/(70-35)+4-60=0
12*[25/(70-35)+4 = 0+60
12*[25/(70-35)+4 = 60
25/(70-35)+4 = 60/12
25/(70-35)+4 = 5
25/(70-35) = 5-1
25/(70-35) = 1
70-35 = 1*25
35 = 25 deci este fals
